The cancer must be among the most dreaded diseases and more common (unfortunately) of our time. The money has been invested in finding new ways to treat and research to find a cure, is abundant. The results of these studies, moreover, have not always been positive.

Breast cancer
However, a few weeks ago a group of American scientists made a breakthrough in the fight against cancer that can mean a great contribution to the cause.

According to information released, it was possible to isolate a gene involved in 70% of breast cancers have more aggressive and more resistant to hormonal treatments that are currently applied in medicine.

The procedure applied researchers from the Whitehead Institute for Biomedical Research in Massachusetts, responsible for the discovery, was to inject cancer cells with fragments of genetic material able to disable, turn other genes, the intention was to detect which ones are needed development of a tumor.

The results are a big step for the development of new medicines against cancer: it was determined that there is a gene – the PHGDH – which is extremely active in the types of tumors that we are referring.

This feature causes changes in the chemical composition of the cancer cell that produces amino acid serine, which makes the cancer less treatable. It is certainly a contribution to the welfare of many of the women in the future to develop a malignant tumor in the breast.

The advance of medicine is undeniable in certain fields. Now, a team of scientists from the Institute of Technology has developed a device for diseases such as cataracts through a next-generation mobile phone.

Altered by the fact that 250 million people suffering from blindness due to medical reasons that could have been avoided, this group of scientists got down to work to adapt a device to avoid mobile phone and taken to be tested in machines costing more than 3,500 euros.

And while in the developed countries, spending on medicine invested in these machines is not impossible; in the poor it is almost impossible to undergo such testing. So a device adapted to the mobile would be a very important aid so that developing countries restrain this eye disease.

The good thing about this device based on the latest technology and the latest advances in eye medicine, cataract is diagnosed at an early stage of the disease, also contributing to the patient has many years of health and wellness.

From time to time medical studies appear that reaching somewhat obvious conclusions. Everyone’s trying to bring something to the welfare of people, put a warning about diseases or health hazards. But the truth is that sometimes no matter the prestige of the university to investigate whether the results are not entirely new.

Traffic and stroke
This time is a matter of a scientific investigation published in the magazine European Heart Journal environment to the noise of the traffic and its risks for the health, carried out by Danish scientists.

After working for 10 years with 51 000 485 people between 50 to 64 years, scientists found that 1,881 individuals suffered some point strokes. For them it became clear that the physical health of those who participated in the study suffers each 10 additional decibels to the traffic noise. Under these conditions the risk of stroke increased by 10%. Among the elderly of 65, it increases by 27%.

Despite the conclusions reached by the aforementioned team of doctors and Danish scientists, cities and its noise is a reality, as well as diseases associated with their lifestyle and its benefits. Ultimately, the health of the people runs risk in any place.

With reservations that such research requires, especially when found in an early stage, a group of British scientists has managed to transform one type of cells similar to stem cells in hearts of adult mice to function as heart muscle, which represents a breakthrough for coronary patients.

The main conclusion from this study that, sure, will be talking about medicine is that in future it could develop a drug to those hearts that have been damaged by a heart to regenerate themselves.

Until now, patients suffering from heart had no choice but to turn the pacemaker or an organ transplant. Therefore, this study led by medicine expert Paul Riley and published in the journal Nature this week has been hailed as a ray of hope for people with severe coronary disease.

So far, it had reduced the number of people who have heart attack, but the people who were not suffering from any improvement in their welfare. Now, this may change since the zones are dead after the attack could be recovered with this medicine.

The director of this medical study assures that can imagine a person at the risk of to suffer a heart attack taking this medicine that prepare to its heart so that if suffers an attack to the heart, the damage that suffer can be repaired.

The scientists discovered more than 20 years ago how to get stem cells from mouse embryos. In late 1998, after intensive experimental work, a group of researchers from the University of Wisconsin (USA) won the first culture of human embryonic stem cells. From this moment, the cell ancestors have been presented as the great therapeutic hope of the new century.

Whatever the source, stem cells face a common problem in laboratory culture. For these cells to proliferate to obtain sufficient material for therapeutic use have to be grown under very specific conditions.

In stem cells, we find two types: embryonic and adult. The first is also known as pluripotent: Currently used as a model to study embryonic development and to understand what are the mechanisms and signals that allow to reach a pluripotent cell to form any fully differentiated cell of the body.

Adult stem cell known in an adult so far about 20 different types of stem cells, which are responsible for tissue regeneration in continuous wear (such as skin or blood) or damaged (eg, liver). Its limited capacity to generate more specialized cells. Hematopoietic stem cells of bone marrow (responsible for the formation of blood) are the most known and used in clinic for some time.

At the same bone, but also in umbilical cord blood, peripheral blood and in body fat have found another type of stem cell called mesenchymal which can differentiate into numerous cell types of the three embryonic derivatives (muscular, vascular, nervous, hematopoietic, bone, etc). Although not yet its physiological importance has been able to be determined abundant clinical trials are underway to replace damaged tissues (heart) for derivatives of these cells.

Sleep an average of 6-8 hours a day is healthy. European scientists and researchers have conducted a study which shows that sleeping more than nine hours a night is damaging to health, even may be a sign of serious illness. It followed more than a million people for 25 years and there were more than 100,000 deaths around the world.

Sleeping less than 6 hours a day is not recommended, excessive hours of sleep can cause serious problems in both cases can be a cause of major diseases and in isolated cases even death.

In an adult sleep 6 hours a day consistently is ideal, even 5 if it is intense and continuous, with ideal temperature and without noise. Lack of sleep, insomnia or anxiety, is more full-time workers and intensive, all this reduction of hours of sleep, brought about by the social rate, not more slowly than harm mental health, and shown as studies the relationship between lack of sleep and rest, with illness and premature death.

It is preferable to control the hours of sleep, and especially care for the quality of the repair time, in small details, temperature, quietness and comfort. Very important the mental part, never go to bed angry, sad or upset, sleep better after laughing, humor is a vital factor for our rest.

Snacks, healthy, and light food: Mediterranean diet. Just by eating healthy and varied, you’re giving your body what it needs, so this is one of the great secrets of Mediterranean cuisine, typical of Italy, Spain, Greece or France. In it your fish, cereals, legumes, nuts and salads.

Among the benefits of the Mediterranean diet on the body include the ability to prevent asthma. This is due to the large number of antioxidants together with fatty acids like Omega 3, combat asthma and other diseases, such as rhinitis or allergies.

On the other hand, the Mediterranean diet is also effective in reducing blood pressure. Natural oils are good for it, so that hypertensive individuals have in Mediterranean cuisine a source of major health. Some people even dare to say that the Mediterranean diet prolongs life. The Mediterranean diet is good to combat degenerative diseases like Alzheimer’s.

In addition, studies say that the Mediterranean diet is effective in combating certain types of tumors.

Similarly, we can not forget the fruit in the Mediterranean diet, which brings great benefits to the body. In addition, olive oil and nuts are good for protecting the heart. The tomato is another element present in the Mediterranean diet also brings benefits.

IELCAP international study, published recently and included the participation of the University Hospital of Navarra and the Center for Applied Medical Research (CIMA), University of Navarra, and the recent research conducted by the National Cancer Institute (NCI) and funded by the U.S. government, endorse the importance of this diagnostic test in the increased survival of patients with lung cancer.

“We are questioning many things about the changes that are needed”, he added, while also has stated that “if the government does not observe this issue with other eyes will be missing a great opportunity to reduce deaths from a most deadly diseases of our time”.

In addition, the researcher, following the American findings, the debate focuses not only on scientific evidence of the effectiveness of the test if not the cost of the possible implementation of programs ‘screening’ of lung cancer and the criteria to be followed to select populations at risk.

“The question of cost depends on whether there is short or long term. Look at short term, obviously, it is necessary to make investments, not expenses but investments. But in the long term become a savings and to deal with lung cancer in advanced stage is much more expensive and less effective than early detection. Therefore, if the authorities observe this issue in the long term, consider investing in these programs is certainly a saving”, he warned.

Therefore, the expert urges governments to design programs for early detection of lung cancer for the general population. From the standpoint of medical recommends people at high risk of contracting the disease, smokers or former smokers to seriously consider the benefits they can offer this type of evidence.

This is the main element in the fight against pellagra, a disease whose main symptoms are diarrhea, skin diseases and signs of dementia. It is used to combat mental disorders, emotional instability, persecution complex and a feeling of insecurity.

In addition, Vitamin B3 is involved in the processes of digestion and prevent gastrointestinal disorders by a malfunction of the intestinal flora. Also participates in the synthesis of various hormones such as sex, thyroid and insulin.

Without doubt, we need at least a minimum ration of vitamin B3 to keep a good physical and mental. Moreover, we know that consumption, accompanied by alcohol, pills or sedatives, greatly reduces their profits.

Externally, it is also beneficial, since ingesting supplements, vitamin B3 before the summer season, our skin will be more protected from the sun’s rays, reducing its sensitivity. Another very important fact, especially for seniors, is that this vitamin also greatly improves the memory.

The good thing is that the only way to get vitamin B3, is not through supplements, vitamin, but there are foods containing high doses of B3, and help raise levels of it in our body. These foods, which further contains vitamin B3, is the horse, followed by dairy.

The recommended daily dose, around 20 grams for adults, and not more than 10 for kids under 10 years. Furthermore, nicotinamide can be used as in cases of other deficiencies, ingesting a high dose of between 50 and 100 grams daily.
